RISProjection of Summer Precipitation over the Southeastern United States in the Superparameterized CCSM4
Publisher: American Meteorological Society
Abstract: rojections of the hydrological cycle over the southeastern United States are compared between CCSM4 and the superparameterized model (SP-CCSM4). Under the extreme forcing of the representative concentration pathway 8.5 ...
A Deep Learning Filter for the Intraseasonal Variability of the Tropics

The Influence of Atmospheric Noise and Uncertainty in Ocean Initial Conditions on the Limit of Predictability in a Coupled GCM
Publisher: American Meteorological Society
Abstract: The influence of atmospheric stochastic forcing and uncertainty in initial conditions on the limit of predictability of the NCEP Climate Forecast System (CFS) is quantified based on comparisons of idealized identical twin ...
Potential Vorticity as Meridional Coordinate
Publisher: American Meteorological Society
Abstract: The dynamical equations of atmospheric flow are written using potential vorticity as the meridional coordinate and potential temperature as the vertical coordinate. Within this system, the atmosphere is divided into ...
Is Blocking a Circulation Regime?
Publisher: American Meteorological Society
Abstract: The relationship between Pacific blocking and large-scale circulation regimes is investigated. The large-scale circulation regimes are obtained by cluster analysis using the k-means method and tested against significance ...
Projections of the Tropical Atlantic Vertical Wind Shear and Its Relationship with ENSO in SP-CCSM4
Publisher: American Meteorological Society
Abstract: he vertical wind shear over the tropical Atlantic Ocean and its relationship with ENSO are analyzed in the superparameterized Community Climate System Model, version 4 (SP-CCSM4) and in the conventional CCSM4. The climatology ...
Simulations of the West African Monsoon with a Superparameterized Climate Model. Part I: The Seasonal Cycle
Publisher: American Meteorological Society
Abstract: he West African monsoon seasonal cycle is simulated with two coupled general circulation models: the Community Climate System Model (CCSM), which uses traditional convective parameterizations, and the ?superparameterized? ...
Simulations of the West African Monsoon with a Superparameterized Climate Model. Part II: African Easterly Waves
Publisher: American Meteorological Society
Abstract: he relationship between African easterly waves and convection is examined in two coupled general circulation models: the Community Climate System Model (CCSM) and the ?superparameterized? CCSM (SP-CCSM). In the CCSM, the ...
Northward Propagation Mechanisms of the Boreal Summer Intraseasonal Oscillation in the ERA-Interim and SP-CCSM
Publisher: American Meteorological Society
Abstract: echanisms for the northward propagation (NP) of the boreal summer intraseasonal oscillation (BSISO) and associated Asian summer monsoon (ASM) are investigated using data from the interim ECMWF Re-Analysis (ERA-Interim, ...
Intraseasonal Variability in Coupled GCMs: The Roles of Ocean Feedbacks and Model Physics
Publisher: American Meteorological Society
Abstract: he interaction of ocean coupling and model physics in the simulation of the intraseasonal oscillation (ISO) is explored with three general circulation models: the Community Atmospheric Model, versions 3 and 4 (CAM3 and ...
